我正在做一个大项目。我在制作评论回复系统时陷入困境。它适用于 Ajax,但是当我发布第二条或其他评论回复时,文本区域显示为空。为什么只有第一个回复提交成功?这是我的代码:

$(document).ready(function(){
    $(".post_reply").click(function(rp) {
        rp.preventDefault();
        var box_id = $(".bid").val();
        var ownerc = $(".owner").val();
        var replyc = $(".reply").val();
        var commentc_id = $(".comment_id").val();
        var dataString = 'bid='+ box_id + '&owner=' + ownerc + '&comment_id=' + commentc_id + '&reply=' + replyc;
        alert(replyc);

        if(ownerc=='' || box_id=='')
        {
            alert('Please Give Valide Details');
        }
        else
        {
            $.ajax({
                type: "POST",
                url: "sub_comment.php",
                data: dataString,
                cache: false,
                success: function(replys){

                    $('#replys'+commentc_id).append(replys);
                    $(".reply").val('');
                }
            });
        }
        return false;
    });
});

这是评论系统的完整代码..

       <h3>User Comment</h3>
                <div class="comments_area">
        <?php
        $comments=mysql_query('select * from comments where bid="'.$_GET['id'].'"');
        while($get_info=mysql_fetch_array($comments)){
        $comment=$get_info['comment'];
        $comment_id=$get_info['id'];
        $cuid=$get_info['uid'];
        $c_users=mysql_query('select user_name,thumb from users where id="'.$cuid.'"');
        $get_uinfo=mysql_fetch_array($c_users);

        $cimage=$get_uinfo['thumb'];
        if(strpos($cimage,'https://') !== false) {

似乎是 return false;导致问题的原因。

return false;调用时做三件事:

  1. event.preventDefault();
  2. event.stopPropagation();
  3. 停止回调执行并在调用时立即返回。

因此,如果您return false;单击事件将永远不会再次触发。只需使用 preventDefault()。
